A video circulating on the web purportedly shows the incident, which happened late last week. Its authenticity could not be immediately verified.
The footage shows a man shooting a gun in the air and then starting to dance with several other guests to the hit song.
The rattle of gunfire is then heard and when the camera pans down, bodies are seen lying in pools of blood. The music stops as the guests rush to help the victims. Celebratory gunfire is common at Yemeni weddings.
